Limonene Dominant Phenos

Limonene-dominant phenotypes are cannabis plants that accumulate D-limonene—a cyclic monoterpene—as their primary aromatic compound. Limonene is commonly associated with citrus, lemon, and pine aromatics in cannabis, though expression varies significantly across genetic backgrounds and environmental conditions. These phenotypes arise from selective breeding prioritizing terpene synthase enzyme activity and cannabinoid pathway partitioning toward limonene biosynthesis. Breeders working in this category often cross strains with documented limonene expression histories, though actual terpene profiles depend heavily on cultivation, harvest timing, and post-harvest handling. Limonene-dominant strains appear across multiple genetic families, from Sativa-leaning cultivars to Indica-influenced crosses. Understanding limonene expression helps breeders predict aromatic consistency and support trai

Breeders select for limonene dominance through phenotypic screening and progeny testing, using these plants as parents to establish limonene-forward F1 and F2 lines. Limonene expression is heritable but polygenic, making it valuable for creating aromatic consistency in commercial breeding programs.
